BOBBlN-HOLDER FOR SPINNING-SPINDLES.

Specification of Letters Patent.

Patented Dec. 25, 1906.

To to whom it may concern:

Be it known that we, PATRICK J. DUGGAN and JosEPH J. .MCCARTHY, citizensof the United States, residing at the city of Providence, in the countyof Providence and State of Rhode Island, have invented certain new h"and useful Improvements in Bobbin-Holders for Spinning-Spindles, ofwhich the following is a specification.

This invention relates to a bobbin-holder adapted to be secured upon thespindle of spinning-frames and the object of our inven tion is toprovide means to firmly hold by frictional contact a bobbin whenpositioned upon the spindle.

The invention consists of the novel construction, arrangement, andcombination of parts, as hereinafter described and claimed.

In the accompanying sheet of drawings, Figure 1 represents a top planView of our improved bobbin-holder; Fig. 2, a side elevation of thesame, and Fig. 3 a central vertical sectional view showing a bobbinsecured to the holder device.

Like reference-letters indicate like parts.

A designates our improved bobbin-holder as a whole, comprising in itsstructure a circular cup-shaped supporting member and three coil-springssecured thereto, respectively. The supporting member is in the form of adisk 5, having three upwardly-extending integral flanges c c 0 formed atits outer edge, and which flanges are each provided with a row of smallperforations through their upper portions, as at d d in Figs. 2 and 3.The upper portion of each flange c of the holder member is surrounded bya coil-spring e, which is of round steel wire, and each spring issecured in place by having its wire passed through each perforation ofeach flange of said member. The support or holder member has a hub fformed centrally of its bottom I), projecting downwardly therefrom, andthis hub is provided with a tapering opening 9 of a size to fit thatportion of a tapering spindle to which said member is securely fastened,as at a point h.

j represents the bobbin of a spinning-frame, said bobbin having theusual V-shaped groove or score formed around the exterior surface of itshead and near the base end thereof, as at 7r. This head portion of thebobbin is of greater diameter than the diametrical distance betweenthesprings 6. Therefore when the bobbin is mounted and forced downwardlyon the spindle the bobbin-head ex ands the springs, and the moment thebofibin is seated upon the supporting member these springs contractWithin the groove k and cause the bobbin to be held firmly in positionby friction in the manner shown in Fig. 3. The coil-springs being ofround wire presenta large smooth holdingsurface while the bobbin ispositioned.

By our construction and arrangement of parts we produce a bobbin-holderthat is simple, durable, and inexpensive to manufacture.

What we claim, and desire to secure by Letters Patent, is--- 1. Theherein described bobbin-holder, comprising a disk having outerupwardly-extending integral flanges which are each provided with a rowof perforations and said disk having a central hub provided with anopening therethrough, and coil-springs surrounding the upper portion ofthe flanges of said disk, and each of said springshaving its wire woundthrough the perforations in the flanges thereof.

2. The combination, with a spindle, of a bobbin-holder, comprising adisk member centrally secured to the spindle and having outerupwardly-extending integral flanges which are each provided with a rowof perforations, and coil-springs whose wire is wound through theperforations in the flanges of said disk and arranged to grasp theexterior surface of the bobbin-head, substantially as set forth.

In testimony to the foregoing we have subscribed our names in thepresence oftwo witnesses.
